LOCK SWITCH.

Application filed October 16, 1916. Serial No. 125,788.A

To al? whom it may concern:

Be it known that I, HARRY A. CLUM, a citizen of the United States, andresident of lVauwatosa, in the county of Milwaukee and State ofWisconsin, have invented new and useful Improvements in Lock Switches,of which the following is a description, reference being had to theaccompanying drawings, which are a part of this speciiication.

This invention relates to improvements in lock switches moreparticularly, although not solely, adapted for controlling electricignition and lighting circuits.

In automobiles or other self propelling vehicles it is the usual customto provide' means for locking the switch controlling the ignitioncircuits to prevent the surreptitious use of the vehicles. It is alsothe custom to combine both the ignition and the lighting switch in aunitary structure to reduce cost and size, and when thus combined onlythe ignition is locked. This arrangement permits the surreptitiousturning on of the light circuits and consequently considerable currentis wasted and at times the battery is exhausted.

Furthermore the sparking at the points of the ordinary make and breakcontacts causes injurious pitting and sticking of the parts and is notconducive to the smooth running of the engine controlled by the switch.

It is one of the objects of the present invention to overcome] thebefore mentioned objectionable features and provide a unitary lockswitch for controlling both ignition and lighting circuits in which theswitches controlling both circuits may be locked by a single key.

A further object of the invention is to provide a lock switch in whichone of theswitches is unlocked by the insertion of a key and the otherswitch is unlocked by a partial turning of the key, both switches beingautomatically locked when the key is withdrawn from the lock.

A further object of the invention is to provide a lock switch in whichthe polarity of the contact points of the ignition switch isautomatically changed each time the` switch is turned off and on toeliminate the injurious pitting and sticking of the contact points.

A further object of the invention is to provide a lock switch in whichthe parts are locked together by means of a plurality of reclprocaltumbler plates controlled by a key having its opposite edges of reverseirregular shape.

A further object of the invention is to provide a lock switch in whichthe key is locked to the switch and can not be removed while theignition portion of the switch is in the on position.

A further object of the invention is to provide a lock switch in whichthe parts may be assembled in construction or separated for repairs in avery simple manner.

A further object of the invention is to provide a lock switch in whichthe ignition circuit portion of the switch may be locked by turning thekey to any one of a plurality of positions. a I

A further object of theinvention is to provide a lock switch which is ofsimple construction, is strong and durable and is well adapted for thepurpose desired.

With the above and other objects in view the invent-ion consists of theimproved lock switch and its parts and combinations as set forth in theclaims, and all equivalents thereof.. A

Fig. l() is a detail view of a portion of the casing; and

Fig. 11 is a diagrammatic view of the electrical connections showing theswitch members in their oli'l positions.

Referring to the drawings the numeral 12 indicates the casing orsupport, 13 the torwardly projecting tubular extension or barrel and 14:the rear cover or plate which is formed ot insulating material. Thecasing is of cup-like shape with its bottom portion 12 forming the frontend of the casing and on which end a dial plate 15 is rigidly mounted.The central portion of the casing end is provided with an opening 16 toreceive the inner open end of the extension or barrel 13 which is alsorigidly connected thereto. rllhe casing barrel 13 is formed otcomparatively thin metal and is provided with elongated peripherallocking slots 17 and an outer end opening 18 oi less diameter than thebore 19 of said barrel to torni an annular shoulder 20. The lockingslots 17, ot which there are preferably four, are spaced equi-distantcircumferentially from each other and are of a width corresponding tothe width of the transversely extending tumbler slot 21 of the lockcylinder 22 which is revolubly mounted in the barrel 1S.

'llhe lock cylinder 22 is formed lwith a reduced forward end portion 22which projects through the reduced outer end opening 18 of the barreland the shoulder 23 formed by said reduced portion vabuts against theshoulder 2O of the 'barrel and properly positions the two parts withrespect to each other. A key slot 211 of irregular sha-pe transverselyextends longitudinally through the central portion of the lock cyl- Vinder and intersects the transverse tumbler slot 21. 'A key 25 havingits two opposite edges 26 of reverse irregular shape and its widthapproximately the same throughout its tumbler engaging portion, isshaped or corrugated transversely to fit the key slot and is adapted toextend through the elongated medial openings 27 of he fiat tumblers 28reciprocally mounted in the cylinder slot lwhen said key is inserted inthe key slot.

shape' conforms approximately to the edge contour of the portion of thekey engaged by the tulnblers'when said tumblers are in alined unlockedposition as shown in F ig. li. l/ihile the tumblers are arranged to fitthe particular key shown it is obvious that the arrangement/0I" thetumblers may be changed or the distances between the medial openmay bevariedtol rit various shaped incassakeys so that no two locks may becontrolled by the same key. When the key is withdrawn from the lock thetumbler openings will be in alined position with respect to each otherand the outer ends of the tumblers will be out of alinelnent with eachother and project through the locking slots 1T ot the barrel 13 and lockthe cylinder to the barrel. rllhe opposite ends of the tumblers 28 arenotched or recessed transversely as indicated by the numeral 29 toreceive the inwardly extending radial locking ribs or teeth 30 of thehub 31 ot' the locking switch lever The said hub portion 31 surroundsthe barrel and the outer projecting end ot the cylinder' and bearsagainst the iace otl the dial with an annular portion 33 of the hubextending into the center opening 84e of the dial 15. The locking ribsor teeth 30 bear against the periphery ot the barrel and are sopositioned as to register with the locking slots ot the barrel when theswitch lever is turned to either one of its three positions to permitthe outer ends ot the tumblers to project through the barrel slots andinto the interspaces ot the teeth of the switch lever and thus lock thecylinder and the switch lever to the barrel.

The hub portion of the switch lever is maintained in position againstendwise movement on the barrel by means ot a segmental member whichbears against the inner face of the end of the casing and is providedwith projecting lugs 36 which extend through diametrically oppositesegmental slots 37 in the casing end and engage the inner face of thelever hub. Screws 8S extending through the segmental member and thesegmental slot-s and threaded into the lever hub secure the two partstogether.

rllhe peripheral locking slots 17 of the barrel are spaced equi-distant'from each other in pairs diametrieally opposite to each other so thatthe lever and the cylinder may be locked to the barrel when the key isturned into register with the barrel slots, and

when the key is turned to an intermediate position it will register withthe sidef portions 39 of the barrel between theslotsand these sideportions will prevent the recip- 'z rocation of the tumblers tmm theirinnermost position and prevent the withdrawal ot the key from the lock.

ln order to insure the rotation ot the cylinder always in the samedirection the inner end portion of the cylinder is formed with ratchetteeth 4() which are engaged by a spring actuated dog 41 mounted on theinner face of the easing end.

The periphery of the segmental member 35 is formed with notches orrecesses 452 which are respectively engaged by a medial portion ot theresilient dog 4:3 positioned within the casing. These notches correspondto the three positions or switch liti lever and releasably hold thelever in either one ot its positions.

The casing 12 is provided with a cup shaped movable partition 4d havinga centra] opening #l5 and a locking linger t6 projecting inwardly fromthe annular tiange i7 of the partition. rlihe partition tits within thecasing with its flange extending outwardly and its inner. end portionisrigidly connected to the segmental member and to the switch lever bythe rscrevrs 38 betere mentioned.

A lighting contactv ring d8 positioned within the casing and the flangedportion i7 ot the partition is formed with peripheral locking recess 19to vreceive the locking finger 46 of said partition and cause said ringto turn with the partition. The contact ring is ormedof insulatingmaterial and its rear side face is provided with an annular groove 50and three recesses 5l intersecting said groove to receive lightingcontact plungers 52 reciprocally mounted therein. `The lighting plungers52 are elec-l trically connected together by a flexible cable 53 and areprovided with coiled springs 54 to resiliently maintain their workingends bearingl against the inner face ot the rear cover or plate 14. Thesaid plate 14.- is provided with lighting contacts 55 in circumterentialalinement with the plungers 52 and these contacts are adapted'to beconnected to lighting circuit wires56 and wire 57 leading to a batteryor other source of electrical energy. These connections provide forturning the respective lamps 58, 59 and 60 on or'otf las' the plungersare swung into or out of engagement with the cont-acts by means of theswitch lever 32. The combination of lamps shown may be changed in anymanner desired without departing trom the spirit. and scopei of theinvention.

An ignition switch member 6l positioned within the bore of the lightingring member 48 is removably connected to the lock cylinder 22 by pins 62which project from the inner end of the cylinder and enter recesses 63in the switch member 61. This switch' member 61 is provided with fourrearwardly extending spring pressedcontact plungers 6l and 64, similarto the lighting contact plungers 52, which ar'e connected together inpairs by fiexible electrical cables 65 to permit independentreciprocation oit' said plungers in the recesses. 66 oit` `the saidswitch member 61. These contact plungers 64 resiliently bear against theinner lace or? the rear plate 14 and are movedinto engagement with fourignition contacts 67 and 67 which are mounted in said plate. @ne of thecontacts 67 is connected to the bat tery Contact 55 by a wire 68 and oneof the contacts 67 is connected to a .binding post 69 by a wire 70 andfrom thence to ground by a ground circuit wire 71.l The/other two`contacts 67 and 67 are connected to an ignition coil 72 or other deviceby circuit wires 78 and 7-2 and spark plug 75 is shown as connected tothev coil and to the ground. By the provision oit the pairs of plungers54; and 6d and the contacts 67 and 67 every quarter turn of the key 25,.which turns the ignition switch member 61, will reverse the polarity ofthe ignition circuit and eliminate pitting and sticking at the points ofmaire and brealr between the plungers and the contacts. A-.s the lockcylinder can only be turned in one direction each time the ignition isturned oli and on the said polarity will be automatically reversed.

rlille rear cover or plate 14 is removably held in position by means ofthree pins 76 and 77 which engage bayonet slots 78 and an opening 7 9 inthe case. The pins 76 are inserted in the bayonet slots andthe plate isturned a slight distance'until the pin 77 which is of a spring plungertype is in register with the opening 79 to permit the pin to be forcedoutwardly into locking engagement with the opening 7 9 of the casing.

Assuming that the parts of the switch are in the position shown in Figs.1 and 11 both the ignition'and lighting circuits are broken ordisconnected and if the key be withdrawn from the switch both switchmembers will be locked in the oii position. lf the key is now insertedthe tumblers willbe reciprocated to permit the lighting switch to beturned to complete the circuit to the head lights or to the dimmerwithout in any man- Bilv roc

ner adecting the ignitioncircuits. lf it is now desired to complete theignition 4circuits 4the lrey is given a one eighth turn or the distanceof one locking dog tooth and this 'movement will complete the ignitioncircuits in reverse polarity 'from the previous on position and at thesame time lock the lrey in the cylinder as the tumblers are in alinedposition with the side portions of the barrel and cannot be reciprocatedto permit the withdrawal oit the key. llt will also be noted that inturning the ignition circuit on or oil1 that the lighting circuit switchis not moved Vtrom its position oil adjustment.

t will also be noted that while both j switch members may be..independently moved while the key is in the cylinder that when the keyis withdrawn both switch .members are. in'locked position and theignition switch member is in ofi' position.

From the foregoing description it will be seen that the loclr switch isof very simple llO ico

construction and is well adapted for the puri pose described.
